Answer:
(i). Valency of an element is a measure of its combining power with other atoms when it forms chemical compounds or molecules.
(ii). Atomic size is determined by the atomic radius. For an isolated atom, its atomic radius is the distance between the center of the atom (i.e. center of its nucleus) and its outermost shell.
iii.Groups and periods are two ways of categorizing elements in the periodic table. Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period.
iv.Metallic character refers to the level of reactivity of a metal. Non-metallic character relates to the tendency to accept electrons during chemical reactions. Metallic tendency increases going down a group. Non-metallic tendency increases going from left to right across the periodic table.
